    ObjectiveTo test the reliability and validity of the Oswestry Disability Index (ODI) in patients with low back pain in China.MethodsEighty six patients (female 51, male 35, average age 39.5 +/- 10.1) with chronic low back pain were assessed with the ODI. The assessment was repeated 48 hours after the first test.ResultsThe Cronbach' Alpha coefficient for the ODI was 0.891. The intraclass correlation coefficient (ICC) for the repeated tests was 0.854 (95% CI = 0.775-0.905). The exploratory factor analysis extracted two factors, which accounted for 61.91% of the total variance. Significant correlations were found between the ODI and the 6 domains of the SF-36.ConclusionThe Chinese version of Oswestry Disability Index has satisfactory reliability and validity. It can be used as an instrument for assessing chronic low back pain-related disability.
